Learn programming 2: Download Processing. Use point() and line()

Download Processing from www.processing.org and do some exercises with point() and line(). We are introduced to using coordinates to access pixels on the screen. A coordinate has a X and a Y value. The X value is the distance from the left border of the display. The Y value is the distance from the top border of the display. Using an X,Y pair you can locate any pixel on the screen. The top left pixel is located at 0,0. The pixel at 10,30 is found at 10 pixels from the left border and 30 pixels from the top border.

Hello and welcome

This is the first lesson

I'm going to be teaching some programming

we will do some simple graphics

and simple animation

we are going to be using

a language called Processing

The first thing we will need

is to download this Processing software

The website is www.processing.org

Now that I'm in this website

I'm going to read the first phrase

to get an idea what this is about

Processing is an open source programming language

and environment for people who want to create

images, animations and interactions.

Initially developed to serve as a software sketchbook

and to teach fundamentals of computer programming

within a visual context, Processing also has evolved

into a tool for generating finished professional work.
